My invention relatcs to decatizing and more particularly to decatizingcylinders of cloth treating machines or the like.

Heretofore, it has been the practice to employ machines wherein thedecatizing cylinders are of a length corresponding approximately to thewidth of the cloth to be treated. Inasm'uch as various widths of clothare often treated in one establishment, it necessitates theestablishment being equipped with a number of machines having cylindersof lengths corresponding approximately to the width of the cloth for thereason that it is not practical to treat a relatively narrow width ofcloth by the employment of a relatively long cylinder and itscorrespondingly wide blanket because the margins of the blanket wouldextend beyond the edges of the cloth and thus absorb and becomesaturated by moisture produced by the condensation of steam. When themargins of the blanket are thus moisturized, the

, '6 Claims. (Cl.68--8) cloth being treated tends to absorb themoisture' in a manner wherein the cloth becomes spotted or water-markedand thus damaged. Obviously, it is impractical to treat cloth of awidth' greater than the length of the cylinder and the width of theblanket. Inasmuch as the machines are quite expensive, it will beappreciated that quite an investment is necessary to provide a number ofmachines with different length cylinders in order to have available, inone establishment,

means for treating cloth irrespective of the width thereof.

My invention overcomes the necessity of-equipping an establishment withmachines having cylinders of lengths for'accommodating the various sizesof cloth, it being one of the objects ofmy invention to providedecatizing means which is so constructed and arranged that various sizesof cloth may be treated thereby without danger of the 'aforementioneddamage.

' Another object of my' invention is to provide vide decatizing meansincluding a cylinder having a plurality of cloth treating -zones denedand rendered efiective by compartments within the 2 cylinder togetherwith means for rendering the compartments efiective in a selectedmanner.

Another importantobject of my invention is to provide means of theforegoing described character which is simple in construction, durablein use, eficient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear,the invention consists in the combination and arrangement of partshereinafter set forth and illustrated in the accompanying drawingsromwhich the several features of the invention and the advantagesattained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like refera ence characters designatelike parts throughout the several views:

Figure 1 is a diagrammatic View illustrating textile treating apparatushaving my invention incorporated therein. p

Figure 2 is a longitudinal sectional view, partly in elevation, of thedecatizing cylinder constructed in accordance with my invention.

Figure 5 is a sectional View taken on the line 5--5 of Figure 2.

Figure 6 is a detail sectional view taken on the line 6--6 of Figure 2.

In practicing my invention, as diagrammatically illustrated in Figure 1of the drawings, I provide'a decatizing machine or apparatus having adecatizingcylinder 5, cloth loading and unloading rolls 6 and 1, guideand blanket straightener rollers 8 and 9, and a ternary of blanketsupply rolls !0, and !2, respectively. The rolls 6 and 1 are disposed onone side of the cylinder 5 while the rolls !0, l! and !2 are disposed onthe opposite side with the blanket straightener roller 9 being arrangedsubjacent the cylinder 5.

The decatizing cylinder 5 comprises a hollow cylindriform body having acircumferential wall !4 provided with perforations !5 throughout itslength and circumference and with sinistral and dextral end walls !6 and!1, respectively. The body is also provided interiorly with a pair ofspaced partitions or walls !B and !9, thewalls !6, !8, !9 and !1defining sinistral end, intermediate and dextral end compartments 20, 2!

and 22, respectively. The circumferential wall !4 is provided with aternary of cloth treating zones 24, 25 and 26 defined by thecompartments 2, 21 and 22, the widths of the zones 24, 25 and 28, in thepresent instance being approximately twelve, forty-two and twelveinches, respectively.

The end walls 55 and l'l are centrally mounted for rotation uponstationary bearings 21 and 28 with the latter having extendingtherethrough a -pair of conduits 29 and 30, respectively. The inner endsof the conduits 29 and 30 communicate with the compartments -2'I 'ana22, respectively, with the innei' end of the condui't 29 extendingthrough the wall [9 and having sealing engagement therewith by means ofa packin'g joint J to permit rotation of the wall 13 ;relative to theconduit 29. The conduits 29 and 30 have extending therethrough siphontub e's `3 ah-a 32 which have their inner ends rght aI-gularly ben t andterminating in proximity to the bottom of the compartments 2| and 22,respectivel'y. 'The hearing 21 is provided with a conduit 33comf"hthe'compartment 20,'theonduit g prvae'd with a `'sli phon *tube 34having er 'end right-angularly 'bent and terminatm' proximity 'to thebottom of the compart- ^2o in the same mann-er a's 'th'e tubes 31 and'32.

about the zones 24, 25 and 26. Obv iously, a length of relatively narrowmaterial of approximately twelve inches may be treated by disposing thesame, together with a suitableblanket, about the zone 24 or 26. When thematerial to be treated is thus disposed about the zone or zones, thecompartments, defining the zones thus being utilized are suppliedwithsteam.

From the foregoing, "it "will be appar'ent that my inventionprovidsmeans wher'eby textile material of various widths may be treated by asingle cylinder, the steam being supplied to the material through a,selected compartment or compartments according to the width of thematerial to 'be 'treated While in the present instance, I have disclosedmy invention as being con- 'stfuc'tdin 'a 'marner to accommodatematerial of be understood that the cylinder may be divided into agreater'or -lesser number ef compartments 'tha-n that disc'losed andequipped with steam 'supplying and removing conduits and-siphonn tubesfor each of the compartments provided.
